tELEASE-RIGGING.

$pecification of Letters Patent.

Patent-ed July s, 1913.

Application filed September 24, 1909. Serial N 0. 519,479.

To all whom it may concern Be it known that I, "WALTER P. MURPHY, a citizen of the United States, and a resident .of St. Louis, in the State of Missouri, have rigging on the line 2-:-2; and Fig. 3 is an- ,end elevation of the car, broken-away, with my rigging applied.

"1 represents the end sill of a car which a coupler of standard type, having the-usual locking pin 3.

at ares'uitable bearings secured to the face of the end. sill. These bearings may consist f of eye bolts or may be of suitable castings.

is the hand operated lever loosely journaled in the bearings 4, the outer end of which is provided with a crank 6 of such length that the lower end thereof will hang below the bottom face of the end sill, as clearly shown in Fig. 3.

7 is a crank'formed integral with the inner end of the hand operated lever 5 and positioned at right angles to the crank 6. This crank is more or less deflected, as shown in Fig. 1. v

8 is a lever bent to form' an integral arm 9, which terminates in an eye 10, said eye being adapted to he slipped over the crank 7 and the bearing rod 5 and in its normal position, it is situated between the crank 7 and one of the bearings 4C. The eye is of such diameter that there is no material fric- 'f tion between it and the rod 5. The inner end of the lever 8 has a return bend forming a hook 11. The lever 8 is of such diameter that it is adapted to readily pass through the eye 3 of the standard locking pin. 'To elevate the locking pin, the rod 5 is revolved by means of the crank 6, whereupon the crank? is elevated carrying with it the lever ,8,,'?ywhich in turn elevates the locking pm. This construction is such that the draw bar islfree to move backwardahd forward or sidewise without damage. 'In the event of the" drawbar dropping byreason of-a break I, in the draft rigging, the crank 6 will be thrown against the end sill, so as to. prevent a complete revolution of the bar the crank i is sustained, which results in the locking-pin being withdrawn,- whereby the car with the damaged coupler will be aut0- 'matically released from the balance of the train, thus preventing an accident.

What I claim is 1. A release rigging comprising a hand operatedlever, a crank on the inner end of said lever, a pin operating lever loosely journaled on the hand lever, having a floating bearing on the hand lever, whereby the pin lever may be swung bodily on its journal.

2. A release rigging for car couplers comthe crank of prising a rod mounted on the end sill of the car and provided at one end with a normally horizontal crank and at the other end with a normally vertical handle a pin lifting lever attached at one end to the locking pin and fulcrumed at, its other end on the hand I operated rod, the crank of said'rod engaging the pin lifting lever between the lock-, ing pin and its fulcrum.

3. A release rigging comprising a revoluble hand operated rod having a crank at its so inner end, and a pin operating lever having a right angle bend at its outer end terminating in an eye by means of which the pin lever is loosely journaled on said hand lever,

.the pin lever having a floating bearing on 35 the crank of the hand lever.

4. In a coupler pin controlling device, 111

combination, a horizontally disposed shaft having a crank arm at its inner end, a lever slidingly fulcrumed on the shaft and having a shoulder intermediate of its ends, the free end of the lever being adapted for attachment to a coupler pin, and sliding. connection between the crank arm of the shaft and the lever and engaging the lever between its shoulder and its free end.

5. A release rigging comprising a revolu ble hand operated rod having a crank at its inner end, and a pin operating lever deflect-' ed at its outer end toward said rod and ter- I minating in an eye, by mean f which the pin lever is loosely journaled or). said hand lever the pin lever having a floating bearing on the crank ofthehand lever.

6. In an uncoupling device for car-couplers,-the combination with a car trams and locking pin, of-a 'revoluble hand operated rod journaled hearings on the car frame 5, whereby 55 the pin lever 65 and-formed with a handle at its outer end floating bearing on'the Crank of the hand and a laterally extending arm at its inner lever. end, and a pin lifting lever, between its ends extending in the path of said arm, atits inner end releasably engaging said looking pin and provided with means at its outer end for pivotally and 'slidably engaging said shaft the pin'lever having a two witnesses.
